AXLE-BOX.

Application led May 28,

To all whom t may concern.'

Be it known that I, ROBERT C. O sGooD, a citizen of the United States,residing at Claremont, in the county of Sullivan and State of NewHampshire, have invented certain new and useful Improvements in Axle-Boxes, of which the following is a full, clear, and exact specification.

My invention relates to axle boxes. It has for its object to provide an.1mproved axle box construction especially adapted to use in connectionwith axles of the drop axle type. A further obJect of my invention is toprovide an improved axle box construction whereby the requisite drop inthe axle of a dro axle truck is minimized at the same time that boringof the axle is also eliminated and a rigid connection is provided whichpermits the parts to be readily and securely assembled or readilyremoved for replacement when necessary.

In the *accompanying1 drawings I have shown for purposes of ilust-ration, lone embodiment which my invention may assume in practice,the same being illustrated as applied to a mining machine truck.

In these drawings,- ,i

Figure 1 is a side elevation of such a truck equipped with myimprovement2 one front wheel being removed to facilitate illustration.

Fig. 2 is an enlarged detail bottom plan view of an axle box.

Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 2, the boxbeing shown on the truck and a broken away to facilitate illustration.

Fig. 4 is a sectional view on the line 4-4 of Fig. 3, showing the dropaxle 1n elevation and the truck frame and a plurality of axle boxes insection.

In this illustrative construction I have shown a truck 1 adapted toreceive a mining machine and to transport the same from place to placeover rails 2, the truck shown being of the so called drop axle type,adapted to use in mines where there is little head room, and having itsaxles connected to the truck body by improved means.

In my improved construction, the front and rear axles 3 and 4 and theaxle boxes for the opposite ends of each, are preferably of identicalconstruction so that a description of one axle and its axle box will.Sufc for all, Referring @91's Partlulerly Specification of LettersPatent.

cult U-shaped so called drop portion of the latter beingV Patented Dec.6, 1921. 1920. serial No. 385,011.

to the axle box illustrated in Fgsf 2 and 3, it will be noted that thesame comprises a box member 5 having a transversely extending groove 6between its ends of slightly it will be noted that the box is held inposiof screws 11 and 12 which l tion by a plurality are threadedlyengaged in blocksv 13 and 14, these blocks being provided with suitablethreaded longitudinally extending apertures to receive the screws 11 and12. These screws are held definitely in any relative position to themembers 13 and 14 by lock nuts 15 and 16. Thus, it is possible bytightening the bolts 9 to securely clamp the axle to the bottom of theframe 1 in any desired longitudinal position of adjustment of the boxand axle, and by screwing out and locking the screws 11 and 12 so thatthey coperate with the box clamping box against longitudinal movement.

By this improved construction, it will be observed that it is possibleto provide a construction wherein without in any way sacrificingcoinpactness of the truck, the diffiof the axle is reduced in depth insuch a manner as materially to facilitate the forging operation. It willalso be observed that through, the provision of the clamping means setforth, all necessity for boring and thereby weakening the drop axles isobviated at the same time that construction is produced which is capableof being readily replaced when desired.

While I have in this application specifically described one embodimentwhich my invention may assume in practice, it will be understood thatthe same is used for illustrat-ive purposes and that my invention may bemodified and embodied in other forms without departing from its spiritor the scope of the appended claims.

What I claim as new and desire to secure by Letters Patent is:
